Impression Making For Feeding Obturator Appliance In A Cleft Palate Patient : A Case Report.

Cleft lip and palate are some of the most frequently encountered anomalies in the orofacial region. Immediate problems to be addressed in a new born with this defect would be to aid in suckling and swallowing. This article presents a case report of a neonate with cleft palate in whom a feeding obturator was delivered. In this article impression making for fabrication of obturator was discussed.

Management of Complicated Maxillofacial Trauma In Children : A Case Report.

The purpose of this case report was to describe the management of a trauma-induced maxillofacial fracture in a 6-year-old boy. The child was brought to the hospital in an unconscious state with no response to any commands. After primary management, fractured maxilla with mid palate was noted both clinically and radiographically by CT scan. Open reduction with rigid plate fixation was done under general anesthesia.

Effect of surface treatment with remineralizing on the color stability and roughness of esthetic restorative materials / Efeito do tratamento de superfície na estabilidade de cor e aspereza em materiais restauradores estéticos

OBJECTIVES: The purpose of the study was to evaluate and compare the in vitro effect of fluoride varnish, APF gel and MI paste on the color stability and surface roughness of esthetic restorative materials. MATERIAL AND METHODS: 60 disks of each conventional glass ionomer and resin composite were made using molds of 1.2 cm x 2 mm. All the specimens were suspended in artificial saliva for 48 hours at 37ºC. Subsequently, fluoride varnish, APF gel, and MI paste were applied to all the subgroups except the controls. All the specimens were again suspended in artificial saliva and incubated at 37ºC for 24 hours. After incubation, they were cleaned using a toothbrush and toothpaste, and stored in the artificial saliva for 1 week. During this period, the specimens were subjected to color and surface roughness measurement. RESULTS: Measurements were expressed as mean ± standard deviation and compared between two groups by Student’s t test. One way ANOVA was used for multiple group comparison and Tukey’s test for pair wise comparison. CONCLUSION: The deterioration of GIC material was more rapid compared to composites when fluoride varnish, APF gels and GC Tooth Mousse were applied. The use of remineralizing agents on esthetic restorative materials causes changes in color and surface texture.

OBJETIVOS: A finalidade deste estudo foi avaliar e comparar o efeito in vitro do verniz com flúor, do gel APF e da pasta MI na estabilidade de cor e aspereza de superfícies de materiais restauradores estéticos. MATERIAL E MÉTODO: 60 discos de cimento de ionômero de vidro convencional e 60 de resina composta foram produzidos usando moldes de 1,2 cm x 2 mm. Todos os corpos de prova foram mantidos em saliva artificial por 48 horas a 37oC. Em seguida, verniz fluorado, gel APF e pasta MI foram aplicados a todos os subgrupos, com exceção do grupo controle. Todos os corpos de prova foram novamente imergidos em saliva artificial e incubados a 37oC por 24 horas. Após a incubação, eles foram limpos utilizando escova de dentes e pasta, sendo mantidos em saliva artificial por uma semana. Durante esse período, os corpos foram submetidos a medições de coloração e de aspereza de superfície. RESULTADOS: As medidas foram expressas como medianas +- de desvio-padrão e comparadas entre dois grupos pelo teste t de Student. ANOVA foi usada para comparação entre grupos e o teste de Tukey foi utilizado para comparações por pares. CONCLUSÃO: A deterioração do ionômero de vidro foi mais rápida quando comparada com os compósitos pela aplicação de verniz com flúor, gel APF e pasta GC dental. O uso de agentes remineralizantes nas restaurações estéticas pode causar alterações de cor e textura de superfície.
